Specification forming part of Letters Patent No. 137,379, dated April1,1873; application filed December 31, 1872.

of tire-extinguishers, as hereinafter described and pointed out in theclaim.

Figure l is a side elevation of the apparatus which I proposeto use,with a part secl tioned; and Fig. 2 is a sectional elevation of Fig. ltaken on the line Similar letters of reference indicate correspondingparts.

Arepresents a pipe, connecting with the boiler of any kind in whichsteam is main- Itained, which will be arranged to extend around the roomin whole or in part, as may be required by the circumstances ot' thecase. B is a valve-case, with a cap, C, having several nozzles, l),pointing in diii'erent directions, to deliver the steam escaping fromthe pipe A in jets when the valve is open. E is the valve in the top ofthe case B. Its stem F extends up through the cap C, and connects withthe lever Gr, which is pivoted to a fulcrum at H, and is caused to holdthe valve shut by a stick, I, placed under its free end, and resting onthe adjustable seat K. This stick is hollow, and lled ywith powder L orother explosive material, with which a fuse, M, connects, which is to beso extended about the room, and so disposed that it will be ignitedquickly in case of iire in the room,

and explode the stick, so as to free the valve and allow the steam toopen it and escape into the room. N is an extension of the lever with abell-cord, O, attached to the end of the extension for transmitting analarm to other rooms or frequented places, say the office or kitchen.The object of extending the valvelever is to obtain sweep enough by tlheshort movement of the valve to obtain the requisite movement of thebell-cord.

As many of these steam-discharging devices as prefered will be placed ina room, and the pipes will be arranged in any suitable or approved wayfor extending them throughout all the rooms, and having theextinguishing apparatus arranged in each.

Instead of connecting the valve-lever to the alarm apparatus by a cord,I may have the lever trip a clock mechanism or other apparatus workingan alarm.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- In combination with a valve and releasingapparatus asabove described, the cap C, and nozzles D, substantially as specilied.
